We love our new mailbox. Here’s a tech tip for you. If you have a 4x4 in the ground this works super easy. Cut the 4x4 off 24” off the ground and get yourself a 2’ piece of 2”x6” and 3/4” lumber and apply to the two sides of the 4x4 level. The new mailbox will slide over this perfectly. No digging holes and it may take you 30 minutes max. If ya got some skills 15 minutes:).
This product is super clean and I can guarantee that you will have an original mailbox in the hood. If ya want the rust look quickly, consider paying the extra. It takes a bit for it to start rusting.
